Consider the network setup in the following figure, where the router is a NATed router. Suppose that the ISP assigns the router the address 192.162.30.79 and that the network address of the home network is 172.20.0.0/16.

a. Assign addresses to interfaces 1 and 2, and hosts A, B and C.

b. Suppose host B has an ongoing TCP connection to port 4567 at server 34.182.19.20 from port 80 at host B. The NATed router assigns a new port 8080 for this TCP connection. Provide the corresponding entry in the NAT translation table and the source ip, source port, destination ip, and destination port in each of the four IP datagrams shown below.
